Roof Top Solar
Investing in rooftop solutions leads to great savings, while protecting the environment. Vande Bharat Solar Solutions offers solar rooftop for home. Save and Earn from your idle rooftop space.
A rooftop solar power system, or rooftop PV system, is a photovoltaic system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. With solar on your roof, your power bills will be reduced because you will need less electricity from the grid. The cost of electricity from the grid is expected to rise in the coming years, so your cost saving should also rise also with a linear power warranty of 25 years, you can expect long-term cost savings from avoiding the cost of expensive electricity from the grid.
The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories. A solar photovoltaic (PV) system mounted on a rooftop of a building is a mini-power requirements or feed into the grid. Although anyone can install a solar rooftop system, the size of the installation varies significantly depending on availability of space, amount of electricity consumed by the property and the ability or willingness of the owner to invest the capital required.
Frequently Asked Questions
In a solar rooftop system, the solar panels are installed on the roof of any building like residential, commercial, institutional and industrial buildings.
On-grid means your solar system is tied to your local utility's GRID. ... Being off-grid means you are not connected in any way to your grid's power system or utility company. This is appealing because you are 100% self-sustaining your energy use.
In grid connected rooftop or small solar photovoltaic (SPV) system, the DC power generated from solar panel is converted to AC power using power conditioning unit/Inverter and is fed to the grid.
A 1 kW rooftop system generally requires 10 sq. metres of shadow-free area. However, actual area requirement may vary depending on the efficiency of solar module, and their placement etc.
Rooftop solar PV systems can be installed on any type of roof having sufficient load bearing capacity.
On a clear sunny day, 1 kWp solar power plant can generate 4 to 5.5 units in a day.
The Benchmark cost of Grid connected rooftop solar PV systems determined by MNRE is about Rs. 75 per watt or Rs. 7.5crore per MWp capacity.
Yes, though they produce less electricity. Under a light overcast sky, panels might produce about half as much as under full sun.
It takes about 2-4 weeks to install a smaller system and about 4-8 weeks for larger systems. In certain cases, there may be variations to these timelines on account of access to the site.
To increase the generation of solar power & installed solar capacity, Ministry of New and Renewable Energy (MNRE), of India is implementing Grid-connected Rooftop Solar Scheme (Phase-II). Under this scheme Ministry is providing 40% subsidy for the first 3 kW and 20% subsidy beyond 3 kW and upto 10 kW.
A billing mechanism offering the utility provider to get credits for the excess solar energy produced by your solar panels is net metering. There is a difference between how much energy the solar power system provides and how much is used for your home. So the excess electricity produced is sent to the power grid, and you get paid for it.
This is possible in very rare cases because the consumer shall be required to pay some minimum charges like fixed charges, etc. even if the consumed energy is all selfgenerated. However, ‘electricity charges’, a major component of the monthly bill, can be reduced to zero by optimally designing and maintaining the RTS. The monthly electricity bill may come to zero in States which give revenue for surplus power generated.
The standard life span of solar panels is about 25 to 30 years, if new technologies do come in, it should be fairly easy to "upgrade” your system to fit your electrical needs. Also it is essential for every solar panel systems to be maintained & cleaned every once in a while, to work efficiently & effectively. If not maintained, solar panels might come to a stage of replacing sooner than their standard life.
